Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Methotrexate
- the dose administered: 10 mg weekly for four weeks, followed by 20 mg weekly for four weeks, and then increased to 25mg weekly for the remainder of the study if there is no toxicity as determined at the physician’s discretion (Australian Rheumatology Association Guidelines)
- the duration of administration: 12 months
- the mode of administration: oral tablet

All participants will be prescribed oral folic acid at a minimum dose of 5 mg/week, 6 days/week.

Pill count will be performed at 4 weeks, 3, 6, 9 and 12 months to monitor adherence.

Efficacy
Statistical methods / analysis
We plan to recruit 150 patients with hand OA. We anticipate that about 70% will have had treatment with methotrexate for 6 months or longer so or about 100 patients. To examine determinants for response to methotrexate we will have 80% power to detect an odds ratio of 2.0 or more with alpha error of 5% where the prevalence of the risk factors examined is 20% or more. Assuming that MTX will be associated with a 50% relative reduction in radiographic progression, then with 50 participants per arm, we will have 80% power, with alpha = 0.05, 2-sided significance, to show this effect.

Statistical analyses
Analyses will be conducted in Stata v16 or later. Pain reduction will be analysed using ANCOVA with adjustment for the baseline measure or ranked based techniques in case of major violations from normality. Covariates will include age, gender, BMI and baseline severity of radiographic OA and synovitis.

1. To identify those most likely to respond or oral methotrexate.
Subgroup analyses and logistic regression analyses will be performed to determine whether the following are predictors of response to methotrexate: age, sex, menopausal status (including time from menopause), duration of symptoms, presence of erosive disease (yes/no), presence of MCP joint OA and severity of radiological OA.

2. To determine whether use of methotrexate for 6 months or longer results in less joint damage.
We will examine radiographs on those on methotrexate and those not on methotrexate. The proportion on methotrexate who progress will be compared to those who progress not on methotrexate.
We will examine whether less amount of pain (based on reduction in the total pain score calculated from pain score from 3monthly VAS pain score) is associated with less radiological progression and the effect of MTX on this.

These data will be used to develop a treatment algorithm for use on MTX in hand OA based on identification of those most likely to respond and optimal duration of effect.
